A differential assembly includes an outer differential carrier and a differential case disposed in the outer differential carrier. A ring gear is attached to the differential case using fasteners. An electronic actuation mechanism locks and unlocks the differential assembly. The electronic actuation mechanism includes a stator positioned in a stator housing and an armature. A wire harness is connected to the stator supplying electrical power to the stator. A wire guide is attached to the stator housing. The wire guide includes an attachment section attached to the stator housing and an anti-rotation section. The anti-rotation section contacts the outer differential carrier. The anti-rotation section includes a wire receiving portion positioning the wire harness in an area away from the ring gear and fasteners. A removable cover is attached to the differential assembly, the removable cover is positioned about the electronic actuation mechanism and wire harness.

A power transfer unit for a motive device comprises an outer housing, an inner housing, and a torque transferring clutch. A piston housing is located between the outer housing and the torque transferring clutch. A piston is located in the piston housing. The piston is configured to provide actuation forces to the torque transferring clutch. And, when the torque transferring clutch receives the actuation forces, the torque transferring clutch causes the inner housing to rotate.

A power transfer unit (PTU) for a motive device includes an outer housing and a torque transferring clutch. The PTU also includes a piston housing located between the outer housing and the torque transferring clutch, and a piston in the piston housing. The piston is arranged to provide actuation forces to the torque transferring clutch, and to restrict reaction forces back to the piston housing.

A coupling device () and method of assembly, the device being of the type including a plenum member () disposed at one axial end of the coupling housing (), the method comprising configuring the plenum member () such that each of the required features () is disposed circumferentially between an adjacent pair of fastener holes (H). Next, the input ring gear (R) is installed about the housing () of the coupling device (), from an axial end opposite said plenum member (), into assembly position adjacent said flange portion (). Each of a plurality (N) of fasteners () is inserted through one of the fastener holes (H) and into initial threaded engagement with the input ring gear (R). Finally, by means of a fastener driver, all of the plurality (N) of fasteners () are driven into full threaded engagement, substantially simultaneously, with the input ring gear (R).
